If you check the Control Panel on your Windows 10 PC, you might notice something that doesn’t seem to belong. Even if you’ve removed the program and uninstalled any plug-ins or extensions, there it sits.
So what’s going on? That’s not actually Flash Player. It’s the Flash Applet that’s a legacy built-in part of Windows and Control Panel. If you click on it, you’ll get these options for controlling Flash Settings.
This is just a holdover and is expected to disappear with the next Windows 10 feature update.
